Early times[edit]

Indre-et-Loire is one of the original 83 departments established during the French Revolution on 4 March 1790. It was created from the former province of Touraine and of small portions of Orléanais, Anjou and Poitou.[3] Its prefecture Tours was a centre of learning in the Early Middle Ages, having been a key focus of Christian evangelisation since St Martin became its first bishop around 375. From the mid-15th century, the royal court repaired to the Loire Valley, with Tours as its capital; the confluence of the Loire River and Cher River became a centre of silk manufacturing and other luxury goods, including the wine trade, creating a prosperous bourgeoisie.

Recent years[edit]

After the creation of the department it remained politically conservative, as Honoré de Balzac recorded in several of his novels. Conservative Tours refused to welcome the railways which instead were obliged to route their lines by way of Saint-Pierre-des-Corps on the city's eastern edge. The moderate temper of the department's politics remained apparent after the Franco-Prussian War of 1870: sentiments remained predominantly pro-royalist during the early years of the Third Republic. For most of the nineteenth century, Indre-et-Loire was a rural department, but pockets of heavy-duty industrialisation began to appear towards the century's end, accompanied by left-wing politics. 1920 saw the birth of the French Communist Party at the Congress of Tours. By 1920, Saint-Pierre-des-Corps had become a major railway hub and a centre of railway workshops: it had also acquired a reputation as a bastion of working class solidarity.


Indre-et-Loire is part of the region of Centre-Val de Loire; the neighbouring departments are Loir-et-Cher, Indre, Vienne, Maine-et-Loire and Sarthe. The commune of Descartes is famous for the birthplace of French philosopher and mathematician, René Descartes, who invented the Cartesian coordinate system. However, it was independently discovered by Pierre de Fermat, although Fermat did not publish the discovery. After he was invented the Cartesian coordinate system in 1637, he was died in Stockholm, Sweden in 1650.


The President of the General Council is Marisol Touraine of the Socialist Party.
